Modern computers are good at multitasking. Quad-core devices like the Pi 2 and 3 can share work between their cores, and your programs can run up to four times faster if you know how to code them in parallel. However, this is not always easy.
Programming languages like Python are sequential, executing instructions one at a time. What if you want to use all four cores? Luckily, there is help from the multiprocessing module, which allows parts of your program to run in parallel. To demonstrate how it works, we will adapt a program so that its central part runs in parallel, creating some beautiful fractal images in the process.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
